Switch Type: Limit switch

The CNTD CZ-8166N is a high-precision universal roller lever type limit switch of the CZ series industrial position control switches. Adopting a bidirectional flexible roller swing lever structure, this switch supports omnidirectional triggering from left, right and vertical directions, featuring ultra-flexible actuation and wide adaptive range, perfectly suitable for complex multi-directional mechanical stroke detection and limit protection scenarios. Built with high-strength zinc alloy die-cast housing and fully sealed structure, it owns IP65 dustproof, waterproof and oil-proof performance. Equipped with a built-in double-spring microswitch mechanism, it delivers stable signal output, excellent vibration resistance and ultra-long service life. It is widely used in industrial automation lines, CNC machine tools, conveying equipment, lifting machinery, packaging machinery and other mechanical stroke limit and overtravel protection systems.

- IP65 Full Protection: Integrated sealing structure effectively resists industrial dust, water splash, lubricating oil and humid air, ensuring stable operation in oily and dusty workshops.

- Stable Contact Performance: High-precision double-spring reset mechanism ensures instant switching of NO/NC contacts, no delay or virtual connection during high-frequency cyclic operation.

- Ultra-Long Service Life: Optimized mechanical transmission structure, mechanical life up to 10 million times and electrical life over 500,000 times.

- Universal Standard Installation: Consistent mounting hole size and spacing with CZ/TZ series, compatible with most industrial equipment brackets, easy installation and wiring.

- Strong Environmental Adaptability: Excellent anti-vibration and anti-impact capability, maintaining stable triggering accuracy under dynamic working conditions.
